Engine oil brand Mobil 1 has returned to the billboards of Greater Cairo to celebrate its 20th anniversary with a new Out-Of-Home campaign and great rewards for customers. With ad copy that proudly announces “20 years and counting”, the American brand offers free products to KIA and Chevrolet car owners when servicing their oil filter. Additional information on the promotion is included at the bottom of the ads, as well as the company’s website for curious customers who wish to discover other products from Mobil. The campaign was released during the first week of August and uses uni-poles and billboards on selected locations of Greater Cairo.
